Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a multi-part housing with detachable modules is used, then ease of maintenance and assembly is improved, but device complexity increases due to multiple components
Solution Approach 1:
The housing is divided into multiple detachable modules: receiving module, carrier module, and terminating module. Each module can be independently accessed, removed, or replaced, enabling quick maintenance without disassembling the entire lighting arrangement. The power supply module itself is segmented into ferrite cores, induction coil, and housing components that can be separately handled.
Solution Approach 2:
The power supply module is nested within the receiving module, which is part of the housing. The ferrite cores are nested within the power supply module, with the induction coil wound around the ferrite cores. This nested structure allows compact arrangement while maintaining modular accessibility for maintenance.
2Loss of energy
If ferrite cores are securely connected for effective energy transfer, then energy supply efficiency is improved, but assembly difficulty increases
Solution Approach 1:
The connection between ferrite cores is made dynamically adjustable through the resilient holding basket. The basket can be elastically deformed to release ferrite cores during assembly or maintenance, and automatically returns to its constrained state to secure the ferrite cores for effective magnetic coupling during operation. This dynamic mechanism simplifies assembly while ensuring energy efficiency.
Solution Approach 2:
The physical state of the ferrite core connection is changed from permanently fixed to temporarily constrained. The holding basket changes the constraint parameter of ferrite cores based on operational phase: relaxed during assembly for easy insertion, and constrained during operation for effective magnetic coupling and energy transfer.
3Productivity
If the lighting arrangement is designed for quick maintenance without system shutdown, then productivity is improved, but reliability may worsen due to potential connection issues
Solution Approach 1:
The holding basket is pre-configured with resilient sections that automatically engage with ferrite cores when the power supply module is inserted into the receiving module. This preliminary arrangement ensures that ferrite cores are securely positioned for effective magnetic coupling before the system is activated, maintaining connection reliability while enabling quick maintenance.
Solution Approach 2:
The resilient holding basket performs self-service by automatically securing the ferrite cores in the correct position through elastic deformation. When the power supply module is inserted, the holding basket's resilient sections naturally constrain the ferrite cores, ensuring reliable magnetic coupling without requiring additional fastening operations or complex alignment procedures.
